Madera Acres, California, sits in USDA hardiness zone 9b — a zone band wide enough that plant choice, not possibility, is the interesting question.
Well-matched crops include tomato, artichoke, fig, and california poppy, and the gap between "grows in the area" and "grows in your yard" is closed by soil, sun, and drainage.
Even in Madera Acres, no two yards are alike.

What this means for growing in Madera Acres
Each reading below is measured for Madera Acres itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsMadera Acres runs about 304 days between hard freezes (read from Madera County, the closest normal to Madera Acres) — close to year-round growing.
Frost is rarely the limit here; winter plantings are as real as summer ones, and the harder question is which crops shrug off the summer heat.
Grow cool-season crops through the mild winter, and choose heat-tolerant varieties for the summer beds.

Winter hardiness
MeasuredMadera Acres sits in USDA hardiness zone 9b.
The zone sets which perennials, shrubs, and fruit trees live through an average winter here — a plant rated for a colder zone is a safe bet, one rated warmer needs winter protection or gets treated as an annual.
Match perennials and fruit to the zone before you buy, so nothing you plant is a gamble against the cold.

The kind of country Madera Acres is in
Madera Acres sits in the Central California Valley — EPA Level III, inside the wider Mediterranean California. That is read at Madera Acres's own centroid, and it is not what its county reads: Madera County is mostly Sierra Nevada. The wider page above you is answering a different question about different ground.
What Grows in Madera Acres
Plants matched to Madera Acres's USDA zones 9b, ordered by how much hardiness margin each has here — the ones with room to spare at both ends of this town's band lead. Each links to its full growing profile.
Is it too late to plant in Madera Acres?
Rarely: the season closes in stages, not all at once, and each stage has its crops. Cool-season crops can go in from around Jan 8; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 5 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 6 — long-season crops need about 90 days of runway, quick greens only 30. With almost year-round growing weather, timing is about heat and rainfall more than frost — some bench is always in play.

What an experienced grower watches for around here
In and around Madera Acres, Brownfields runs higher than the national average — 358 sites within ~10 miles of Madera Acres. That's not a problem with your land — it's information about it.
Brownfields: Brownfield sites are former commercial or industrial properties where legacy soil contamination (heavy metals, PAHs, petroleum compounds) may persist.
Check EPA brownfield remediation status — many sites have completed cleanup with institutional controls.

Your land is one point inside Madera Acres
Everything above resolves to Madera Acres as a whole — one PHZM band, read across 5K acres, with hard-freeze dates borrowed from Madera County’s record because no 30-year normal resolves at this town’s own centroid. Your parcel is one point inside that footprint. Slope, tree cover, a low spot that pools cold air, and what is in the soil are all resolved at the address, and none of them are visible at town scale. That is the honest boundary of this page, and the reason the next step is a reading of your own ground rather than a better local average.

How we know this about Madera Acres
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at this town’s own centroid; hard-freeze dates from NOAA 1991–2020 28°F normals at Madera County’s record, because none resolves here; boundaries and acreage from US Census TIGER/Line 2025; the contamination records from the federal sources named in their beats above. Soil is not read at town grain anywhere on this page — there is no town-resolution survey in our data, which is why you will find no soil grid here rather than a statewide one wearing a local label. The resolution ledger below names every figure this page inherited.
Common questions about Madera Acres
When does frost risk typically end in Madera Acres?
The last hard freeze (28°F) in Madera Acres typically lands around Feb 5, per NOAA 1991–2020 climate normals — earlier than the light-frost dates most charts quote. That marks the hard freeze, not the last light frost — lighter frosts keep biting past it, which is why tender transplants here wait until about Feb 26.
When is the first frost in Madera Acres?
The first hard freeze (28°F) in Madera Acres typically arrives around Dec 6, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 22, so the watching starts about Nov 6 — about 304 days after the spring freeze cleared.
How long is the growing season in Madera Acres?
Measured between 28°F hard freezes, Madera Acres sees about 304 frost-free days — roughly Feb 5 through Dec 6, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Feb 26 to Nov 22, about 269 days.
Is the soil safe to grow vegetables in Madera Acres?
The federal record around Madera Acres is a meaningful one — 569 documented sites, mostly Brownfields entries (358), the nearest Brownfields record about 0.4 miles out — so a soil test before new food beds is a sensible precaution here, not a reason to hold back from growing. Remember that proximity to a documented site is information, not a diagnosis of any one yard; the contamination map shows exactly what sits where.
How do I protect my plants from frost in Madera Acres?
From about Nov 6 the job here turns from planting to protecting — the last start even a 30-day crop can finish. As the season closes around the first 28°F hard freeze near Dec 6 (NOAA 1991–2020 climate normals), three moves buy time: row cover or an old sheet over tender plants on still, clear nights; water the soil the afternoon before a freeze, so it holds warmth overnight; and harvest tomatoes, peppers and basil before Dec 6. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
